TAMPING-MACHINE.

SPECIFICATION forming part of Letters Patent N0. 347,920, dated A g 24, 1886. Application filed April 5, 1886. Serial No. 197,870. I (No model.)

To all whom it may concern:

Be it known that I, JOHN W. OARLEY, of Thornton, in the county of Limestone and State of Texas, have invented a certainnew and useful Improvement in Tamping Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which 19 Figure 1 is a side elevation of my improved machine, showing the tamping-barsin raised position, or the position they occupy when the machine is in traveling position. Fig. 2 is a vertical longitudinal section through the machine, taken on line 2 2, Fig. 3. Fig. 3 is a top or plan view. Fig. 4 is a side view of one of the cog-wheels removed, showing a number of operating-cams.

My invention relates to an improvement in machines for tamping, intended more particularlyfor tamping dirt under railway-ties; and myinvention consists in features of novelty, hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the wheels of the truck, to which is supported rigidly in any suitable way a stationary frame, B. I have shown this frame secured to the wheels by means of bars B. (Shown most plainly in Fig. 1,) Resting upon the frame B is a movable frame, 0. This frame C is pivoted to the frame B at one side of the apparatus, the point of pivot being indicated by the letter C, Fig. 3. It will thus be seen that one side of the frame may be moved to throw it at an angle with the stationary frame B. This is done by means of a lever, D, located on the other side of the frame from the pivotpoint, and hinged or pivoted at D to a bracket, D, secured to the under side of the stationary .frame B. This lever is provided with a handle at its upper end, and has a slot, D, in which fits a pin or bolt, D, connecting the lever to the movable frame 0. By moving this lever in either direction the frame 0 may be thrown at an angle to the frame B, and the object is that the frame 0 carries the tampingbars, hereinafter described, which it is necessary (where the ties are not at a right angle to the rails) to shift, so that they will be in line with the ties. If the ties are in line with the rails of the track, the frame 0 would be adjusted in line with the frame B, and should the ties be out of a right angle with the rails the frame Ois adjusted in either direction necessary to bring the tamping-bars in line with the ties.

E represents a frame-work extending up ward from the frame 0. In the upper part of this frame are journaled two cog-wheels, F F, in boxes F, as shown in Figs. 1 and 3. These wheels mesh into each other, and one of them is provided with an operating-crank G, as shown in Fig. 3. Beneath and between these wheels is a pinion or small cog wheel, H. This pinion is supported on a shaft, H, fitting in slots H of boxes H secured to the frame 0. The shaft H may be moved in these slots .to bring the pinion H into engagement with either of the wheelsF F. The shaft H is provided with a thread, as shown in Fig. 3, and

- the cog-wheel H has a thread in its hub, meshing into the thread in the shaft H. The object of this pinion H is to give alateral movement to the tamping-bars by moving the frame E laterally on the frame 0. The connection between the frames E and O is shown at E Figs. 1 and 2, the frame E having notches in its lower ends fitting against the frame 0, so as to permit it to slide back and forth on the frame 0. It will thus be seen that when the wheel His thrown into engagement with one of the wheels F F, the frame E and the tam ping-bars which it carries will be moved toward one side of the machine,when the wheel would be thrown into engagement with the other cogwheel, and then the reverse movement of the frame E and the parts it carries would take place. The wheel H and shaft H. are moved by a lever, J, pivoted at J to the frame E, it having a handle on its upper end and secured to the shaft H at its lower end.

L represents the tampingbars, adj ustably secured to the lower ends of arms L by means of bolts L fitting in holes L. To the upper ends of these arms are secured extensions L, pivoted at L to frame E. The inner ends of these arms or extensions bear against cams M, secured to the cog-wheels FF. As the wheels turn, the cams come against these arms, and, forcing their upper ends outward, raise the tampinghars, and as the cams leave the arms,

springs N, secured at N to the frame E, and

bearing against the arms L, force the tampingbars down, and the dirt is thus tamped or forced under the ties. The inclination of the tamping-bars may be changed or adjusted by means of levers O, pivoted at O to the arms L, and connected to the tamping-bars by means of rods The outer ends of the levers engage in ratchet-bars O, by which they may be held to any adjustment. The lower ends of the springs N are secured to the bars L by means of adjustable clamps N, and the upper ends of the springs are secured adjustably to their supports by set-screws N,- as

shown in Fig. 1.

It will thus be seen that with my improved machine the tamping may go on continuously, and the tamping-bars may be moved automatically from side to side of the machine.

Vhen it is desired to move the machine from place to place, the tamping-bars are raised into theposition shown in Fig. 1,by levers P, hinged at P to the frame E, and provided at their inner ends with bars or arms P, that engage beneath the bars L, as shown in Fig. 1. \Vhen the machine is in this position, the levers P are in the position shown in Fig. 2 of the drawings.

If in case it should be neccssary to raise the ties in tamping under them, it may be done by jackscrews Q, located beneath the frame of the truck at Q, Fig. 3, the cross-pieces 0, portions of which are broken away and shown in dottedlincs in Fig. 3, being connected to the rails by means of simple straps R, as shown in Fig. 2.

In moving the machine from place to place the power may be obtained from the crank G, by which the tampers are operated. In order to do this to one of the shafts upon which the cog-wheels F F are supported (preferably the one upon which the cog-wheel F is supported) is secured a chain-wheel, U, over which passes a chain, U,which also passes around a chainwheel, U, on one of the axles of the truck. This wheel U is shown by dotted lines in Fig. 1. \Vhen the machine is used for tamping, the chain U is of course removed or taken off.
